Autism gene stunts neurons, but growth can be restored, in mice

Brown University researchers have traced a genetic deficiency implicated in autism in humans to specific molecular and cellular consequences that cause clear deficits in mice in how well neurons can grow the intricate branches ...

Scientists identify a genetic basis for healthy sleep

From organisms as simple as worms to those as complex as humans, sleep is a fundamental necessity. But although an estimated 50 to 70 million people in the United States suffer from a chronic sleep disorder, the genetic mechanisms ...

Defect in A20 gene expression causes rheumatoid arthritis

Researchers from VIB (Flanders Institute for Biotechnology) and Ghent University have shown that a defective gene can contribute to the onset of rheumatoid arthritis, an often-crippling inflammation of the joints that afflicts ...

Examining the gene-environment interactions that drive autism

People with autism spectrum disorders all have characteristic behavioral difficulties. Nevertheless, the important heterogeneity of their symptoms remains one of the major questions for scientists and physicians. While a ...

Researchers identify genes related to vitiligo

For the past decade, Richard Spritz's lab at the University of Colorado Anschutz Medical Campus has been searching for potential causes of vitiligo, an autoimmune disease that gives rise to patches of white skin and hair.

Discovery of molecular pathway through which stress affects lupus

Systemic lupus erythematosus (SLE) is an autoimmune disease that affects all the organ systems of the body. This chronic disease includes periods of illness, called flare ups, and periods of remission, when symptoms are few. ...

Study identifies gene expression abnormalities in autism

A study led by Eric Courchesne, PhD, director of the Autism Center of Excellence at the University of California, San Diego School of Medicine has, for the first time, identified in young autism patients genetic mechanisms ...
